This was updated Oct. 20 to reflect changes in the purple, red, orange and yellow tiers.

Q: What is the color-coded county tracking system and how does it affect schools?

A: Gov. Newsom released the “Blueprint for a Safer Economy” on Aug. 28 that changed the way the state monitors counties to determine when schools can open for in-person instruction. However, its principal impact is on when businesses can reopen.

The blueprint includes a four-tiered, color-coded system that tracks counties by the number of Covid-19 cases recorded each day and the percentage of positive cases out of the total number of tests administered, both averaged over seven days. It went into effect Aug. 31, and replaced the previous “county monitoring list.” On Sept. 30, the California Department of Public Health released a new health equity metric that went into effect Oct. 6 and impacts a county’s ability to move between tiers.

What do the colors stand for?

Purple, or Tier 1, indicates that the virus is widespread in the county — with more than seven cases per 100,000 residents or more than 8% of tests results reported positive over seven days. Red (Tier 2) indicates “substantial” spread of the virus, while orange (Tier 3) indicates “moderate” spread and yellow (Tier 4) indicates “minimal” spread of the virus in the county.

If one of the two metrics is higher than the other, the state will assign the county to the color associated with the highest rating. For example, if a county reports six cases per 100,000, but a 9% positivity rate, it will be rated purple.

No public or private schools in counties rated purple can reopen for in-person instruction unless they receive an elementary waiver for students in grades K-6 permitted under Gov. Newsom’s July 17 executive order, or are following guidance for small groups of children, known as “cohorts.” See below for counties that move into purple from red.

Counties that move from purple to red can open for in-person instruction after they have remained in the red tier for 14 days. However, some counties may have stricter rules in place prohibiting schools from opening.

Q. Which counties are rated purple and red?

A. On Aug. 31, 38 of the state’s 58 counties were rated purple, meaning that the virus was widespread and schools could not open except for some elementary schools in counties with daily infection rates between 7 and 14 per 100,000 residents, which can apply for a waiver. The state updates the list every Tuesday.

By Oct. 20, 12 counties were in the purple tier: Glenn, Imperial, Los Angeles, Madera, Mendocino, Monterey, Riverside, San Bernardino, Shasta, Sonoma, Tehama and Tulare. These 10 counties include 333 school districts and 590 charter schools that educate more than 2.5 million public school students, not including private schools.

Counties rated red for at least 14 consecutive days as of Oct. 20: Contra Costa, Fresno, Lake, Marin, Merced, Orange, Sacramento, San Diego, San Joaquin, San Luis Obispo, San Mateo, Santa Barbara, Santa Cruz, Solano, Ventura, Yolo and Yuba. Schools in these counties can open for in-person instruction, since they have been in this tier for at least 14 consecutive days.

Additional counties rated red on Oct. 13: Colusa, Kern, Kings, San Benito, Stanislaus and Sutter. Schools in these counties can reopen for in-person instruction if the county remains in red for 14 consecutive days, until Oct. 27.

Counties rated orange as of Oct. 20: Alameda, Amador, Butte, Calaveras, Del Norte, El Dorado, Inyo, Lassen, Mono, Napa, Nevada, Placer, Santa Clara and Tuolumne.

Counties rated yellow as of Oct. 20: Alpine, Humboldt, Mariposa, Modoc, Plumas, San Francisco, Sierra, Siskiyou and Trinity.

Schools in counties rated orange or yellow are free to reopen for in-person instruction based on modifications outlined in the state’s July 17 guidance and subsequent Aug. 3 guidance.

Q. If a school opens while its county is rated red, then the county moves back up to purple, does it have to close?

A. No. Schools that open while their county is rated red, but then move back up to purple may remain open, but must increase Covid-19 testing for staff. According to reopening guidance released July 17, “schools should begin testing staff, or increase frequency of staff testing but are not required to close” if cases or positivity rates increase countywide.

The state recommends that all schools that are open for in-person instruction test staff once every two months, or 25% of staff every two weeks. A school in a county that moves back into the purple tier should exceed this.

All schools are required to close when at least 5% of staff and students test positive for Covid-19 within 14 days. School districts must close if one-quarter of schools in the districts are closed due to Covid-19 cases. Schools can usually reopen within 14 days after campuses have been thoroughly cleaned and disinfected, public health contact tracing is completed and the county public health department has given its approval.

 

Q. Can elementary schools in counties rated purple apply for waivers to open in person?

A. Yes. Dr. Mark Ghaly, the state’s secretary of Health and Human Service, said on Aug. 28 that schools in counties with daily case rates of 7 to 14 per 100,000 residents can apply for elementary school waivers for students in grades K-6. Schools and districts must consult with employee unions, parents and the community before applying for the waiver, which must be approved by the county public health department in consultation with the state Department of Public Health.

Q. Why did the state change its county monitoring system?

A. The state decided to simplify its previous complex county monitoring system by reducing the number of metrics it was calculating (from six metrics to two) and, instead, creating a four-tiered system. Also, it will change the status of counties every seven days instead of daily. All of this is intended to create a more predictable, easily understandable way to determine when businesses and schools can reopen, Gov. Newsom said, when he introduced the new system Aug. 28.

The previous county monitoring list also included data related to the total number of tests administered daily, the number of people hospitalized with Covid-19, the number of patients admitted to intensive care units due to Covid-19 and the number of respirators available. But Ghaly said those are “lagging indicators” and the state wanted to focus on the earliest indicators that show what is happening currently in communities, so they chose case rates.

Focusing on test positivity rates also allows the state to remind the public about the ways to avoid becoming infected, he said, such as by washing hands frequently, wearing masks, maintaining physical distances of 6 feet and avoiding mixing with people outside of households, when possible.

However, both Ghaly and Newsom said the state can take an “emergency break” from reopenings if hospitalizations and intensive care unit admissions begin to overwhelm county healthcare systems. On Oct. 6, Ghaly said that as schools have reopened, he has not seen any indication that the reopenings have contributed to the spread of Covid-19 in communities.

    “Cases” is never clearly defined but is apparently being extracted from positive tests. A “case” is not someone hospitalized, not even necessarily symptomatic. It is a false standard and the state guidelines are ludicrous. Thank God lawsuits are finally being brought challenging the out-of-control power being grabbed by governors and local officials. The manmade nightmare of the misguided shutdowns must end.

    Change the color code system to a square box with lines horizontal lines running through it start up with 54321 then an empty box. Color blindness prevalent thing. Lines would be a lot less perplexing.

    Shasta County is going Purple as of October 9th, due to 123 new cases at Bethel Church, another 60 case at Windsor Retirement Home owned by Bethel Church. And another 60 cases today alone totaling 270 in Shasta County.

It amazes me that the board members are thinking the K-5 are a safe group; are they considering the special needs kiddos that have no concept of what is appropriate regarding masks, distancing, washing hands and basic boundary awareness with their peers/teachers?

    This one-size-fits-all approach to counties of vastly different sizes doesn't work well. Irresponsible behavior by 18-22 year old students from San Diego State University (which was largely online-only, with very limited in-person courses) have already caused 878 SDSU students to test positive for COVID-19. This SDSU-affiliated COVID-19 hotspot represents 22% of all COVID-19 positive tests in the past 14 days and nearly pushed the entire county of San Diego--with its more than 3.3 … Read More

    This one-size-fits-all approach to counties of vastly different sizes doesn’t work well.

    Irresponsible behavior by 18-22 year old students from San Diego State University (which was largely online-only, with very limited in-person courses) have already caused 878 SDSU students to test positive for COVID-19. This SDSU-affiliated COVID-19 hotspot represents 22% of all COVID-19 positive tests in the past 14 days and nearly pushed the entire county of San Diego–with its more than 3.3 million people spread over more than 4,500 square miles–back into Tier 1 (purple), further jeopardizing not only the local economy with more restrictions on businesses but forcing half a million TK-12 students )and their parents) to remain at home, subject to sub-par “distance learning.”

    Explain how the state’s tiered rating system for such a large county–which would keep students home in school districts like Oceanside Unified or Vista Unified, which are located more than 40 miles away from SDSU’s campus–makes sense?

    Under this one-size-fits-all approach and a waiver process that only applies to elementary school districts, young students who are unlucky to be part of a unified school district will continue to have poor prospects for in-person instruction this school year.

    University of California at San Diego and University of San Diego students returned over the weekend, so now the entire county (hovering at 6.9 COVID-10 cases per 100,000 residents) holds its breath to see if irresponsible behavior by more college students will outstrip the efforts of millions of residents who are following social distancing and face mask guidelines in an effort to reopen schools.
